JACOBUS, l' HONTCLAIB, NEW JERSEY, ASSIGNOR T0 THE BABCOCK & WILCOX COMPANY, OI' BAYONNE, NEW JERSEY, A CORPORATION OF NEW JERSEY BOILEB Application led December 17, 1929. Serial No. 414,645.

This is a continuation' in part of my coending application, Serial N o. 714,787, filed This inventor relates to a novel and im- '5 proved boiler, the novel features of which will be best understood from the following description and the annexed drawings, 1n which are shown selected embodiments of the invention and in which;

Fig. l is a vertical sectional View through 'this type of boiler.

a boiler having my invention applied thereto.

Fig. 2 is a view on the line 2 2 of 1g. 1, and showing one embodiment of the invention.

Figs. 3 and 4 are views similar to Fig. 2, but showing still other embodiments.

Referring now to Fig. 1, I have shown the invention as embodied in a boiler disposed above a combustion chamber l, the boiler comprising a bank 2 of horizontally inclined water tubes connected at opposite ends to headers 3 and 4. Spaced above the bank 2 is a second bank 5, of water tubes, and between these two banks is disposed a superheater comprising, in this instance, a plurality of tubes 6 arranged in a bank, as shown, the tubes being arranged substantlally parallel to the tubes in the banks 2 and 5. The functions of the other boiler structure indicated will be apparent to those skilled in the art and, accordingly, it will not be further described.

Spaced along the horizontally disposed bank of tubes 2, and resting on the top thereof, is a plurality of piers 7, 8 and 9. These piers extend transversely to the length of the tubes in the bank 2 and, in the form shown, may rest upon plates 10 which may form part of an angle having a vertically extending leg 11. This leg may be used to retain the pler against sliding on the bank 2 when this bank is horizontally inclined, as is customary in Resting on top of each ier is a second plate 12 whlchlikewise may have a leg 13 which may be turned down as shown in Figs. 2, 3 and 4, or turned up as shown in Fig. 1.

The superheater tubes rest upon these plates 12, and the tubes in the superheater are preferably held in spaced position by means of a plurality of members contacting with a plurality of vertically spaced tubes in the superheate In the form shown in Fig. 2, these members are plates 14 which have notches in their opposite edges adapted to engage a plurality of tubes. These plates are turned at right angles to the plane in this Iigure, and then slid into position between the tubes, after which they are turned to the p0- sition indicated, wherein they act as spacers for the tubes, and also to'transmit the weight of the tubes to the pier. The plates 14 may be bolted together at their top edges by a transversepiece 15, and they may be bolted to CilLhe legs 13 of the plates 12 at their bottom en s.

Still referring to Fig. 2, the plates 10 are shown as being secured to the upper row of tubes 2 by means of clamps 16, and the weight of the pier and superheater is distributed to the plurality of vertically spaced water tubes by means of members 17 similar to the members 14.

Referring now to Fig. 3, a similar arrangement is shown for supporting the superheater tubes and transmitting their weight to the pier, except that in this case two sets of diagonally extending plates are used, these plates being indicated 18 and 19. It will be seen that these plates extend in opposite di rections with respect to each other, and thus form a better braced and stronger support. Still referring to Fig. 3, it will be seen that the load is distributed to the tubes 2 by means of sinuous plates 20, similar in form to the well known sinuous header used in Babcock and Wilcox boilers. These plates may be installed by slipping onto the tubes before the tubes are connected to the headers.

In Fig. 4, the plates 14 are used as in Fig. 2, for transmitting the load of the superheater, and in the water tube bank there are two sets of plates 21 and 22 disposed diagonally to the tubes and extending in opposite directions.

I claim 1. In a steam boiler, a bank of water tubes in vertically spaced rows, a superheater disposed above said bank, and a support for said superheater comprising members engagng water tubes in a plurality of said vertically spaced rows so as to distribute compression due to superheater load to the engaged water tubes.

2. In a steam boiler, a bank of water tubes in vertically spaced rows, a superheater disposed above said bank and `formed of tubes extending longitudinally of the water tubes, and a support for said superheater comprising members engaging water tubes in a plurality of said vertical y spaced rows.

3. In a steam boiler, a bank of horizontally extending Water tubes, one or more piers resting on said bank, a superheater resting on said piers, and a support for one of said piers engaging a lurality of vertically spaced tubes in said ank.

4. In a steam boiler, a bank of horizontally extending Water tubes, one or more piers resting on said bank, a superheater resting on said piers, and a support for one of said piers comprising a plurality of plates each engaging a plurality of vertically spaced tubes in said bank.

5. In a steam boiler, a bank of horizontally extending water tubes, one or more piers extending transversely of said bank and resting thereon, a support for one of said piers engaging a plurality of vertically spaced tubes in said bank, a superheater resting on said piers and comprising a bank of tubes parallel to the Water tubes, and supports resting on said piers and engaging a plurality of vertically spaced tubes in said superheater.
